Embodiment Construction

[0026] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0027] As mentioned above, in the prior art, due to the obvious false positives and negative negatives in the fault diagnosis of a single monitoring system, it is difficult to completely cover the real fault discovery of railway passenger cars. Therefore, the present invention provides a railway passenger car failure monitoring and evaluation method and system. The specific content of the pr...

Abstract

The invention provides a passenger train fault judgment method and system. The passenger train fault judgment method comprises the following steps: acquiring a plurality of system monitoring data froma plurality of monitoring systems and a base level system; determining a comprehensive fault judgment level for one or more target parameters of the passenger train based on the plurality of system monitoring data; and transmitting the comprehensive fault judgment level to the base level system and / or vehicle-mounted equipment. According to the method, the comprehensive fault judgment level for the target parameters of the passenger train can be determined as required through multi-source acquisition of system monitoring data, so that the effectiveness of fault judgment is improved, centralized operation and centralized management of passenger train operation safety monitoring are realized, and the working capacity and the working efficiency of railway safety monitoring are greatly improved.

Description

technical field [0001] The invention relates to the technical field of railway passenger transport safety, in particular to a method and system for evaluating a failure of a railway passenger car. Background technique [0002] The safety of railway passenger transportation is the top priority of railway transportation work, and realizing real-time monitoring of the operation status of railway passenger cars and comprehensive fault alarm is an important means to ensure the safety of railway passenger vehicle operation. [0003] At present, partial fault monitoring and evaluation can be carried out by using a single monitoring system to use part of the operating state monitoring data of railway passenger cars. However, limited by the conditions of technological development, a single monitoring system still has obvious false alarms and missed alarms in fault judgment, and it is difficult to completely cover the real fault discovery of railway passenger cars, thus affecting the ...
